Title: Liquid-safety rod system for a nuclear reactor
Inventor: AGAZZI ALBERTO
IPC: G21C9/033
Filed: 1968-10-22
Abstract: 1,205,849. Controlling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY. 22 Oct., 1968 [26 Oct., 1967], No. 50154/68. Heading G6C. [Also in Division F1 A liquid-safety-rod system has a reservoir 17 for neutron poison solution below the level of a lower collector 3 connecting the lower ends of tubes 2 (only one shown) which extend upwardly through the reactor core, a poison-solution accumulator 5 with a flexible diaphragm 6 dividing it into a lower chamber 8 for poison solution and an upper chamber 9 for gas pressure connected by means of a quick-acting three-way valve 40, 41, 42 either to a source 11 of high pressure driving gas or to a reference low pressure 13, and an overflow reservoir 15 having an overflow discharge pipe 16 at a level 33 just below the bottom of the reactor core to determine the normal operating level of the poison solution. The discharge pipe 16 leads to the poison-solution reservoir 17 which is at a level below that of the overflow reservoir 15. The lower chamber 8 and the overflow reservoir 15 are connected at their lower ends to the lower collector 3, there being an isolation valve 14 between the chamber 8 and the reservoir 15. During the normal operation of the reactor, all the valves in the system are closed except the valve 40, 41, 42 which is open in the directions 41, 42, resulting in the chamber 9 being connected to the reference low pressure 13. The chamber 8 and the tubes 2 up to the level 33 are filled with poison solution. On an alarm signal, the valve 40, 41, 42 is opened in the directions 40, 41 and the driving gas from the source 11 forces the diaphragm 6 down against the lower wall of the accumulator 5, ejecting the poison solution into the tubes 2. If, after this emergency introduction, circulation of the poison solution is necessary, for example, if it would tend to decompose on heating in the reactor core, the solution is pumped by means of a pump 21 through a three-way valve 43, 44, 45 open in the directions 43, 45 and a valve 46 into the tubes 2 from which it returns via an upper collector 4 and a three-way valve 27, 28, 29 open in the directions 27, 28 to the reservoir 17.  To remove the poison solution from the core, the valve 40, 41, 42 is re-opened in the directions 41, 42 and the high pressure gas discharged towards the low pressure 13. The solution enters the accumulator 5 again by gravity from the tubes 2. To empty the tubes 2, the valves 46 and 20 must be opened, the solution then descending by gravity into the reservoir 17. The tubes 2 may then be washed using a circuit comprising a washing-liquid reservoir 22, a washing-residue reservoir 23, a pump 24 and a valve 25. Washing is effected by opening the valves 25 and 46 and valve 27, 28, 29 in the directions 27, 29 and starting the pump 24.

Abstract: 1,235,935. Demodulating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 Oct., 1968 [2 Oct., 1968], No. 50704/68. Heading H3T. In a demodulator circuit for push pull demodulation of a signal modulated on a carrier, having first and second detector elements 1, 2 connected to receive first and second inputs A, B and connected to an output smoothing circuit 3, the inputs A, B are obtained from the collector outputs of transistors 9, 10 and a carrier modulated signal is applied to the base of the transistor 9 and the input for the base of the transistor 10 is obtained via capacitive coupling 14 from a tapping 13 on the resistive load 11, 12 of transistor 9. The emitter circuit of transistor 9 includes a tuned filter circuit 18-23 tuned to the carrier frequency. The switch S 1  is shown in the position for receiving the 405 line television signal and in the other position is for 625 line reception. The input signal may have a single sideband modulation of the video signal on the carrier and may be supplied to the input 27, 28 from a television distribution cable via a selective pre-amplifier stage. By suitable selection of the resistors 11 and 12 the amplitudes of the outputs A and B are the same magnitude. The emitter circuit of transistor 10 includes a phase shift network 24, 25, 26, 26<SP>1</SP> which ensures that the signal at B is opposite in phase with the signal at A. The output line 6 of the demodulator 1, 2 may be connected directly to the earth line 28 or as shown via RC network 29, 30, 32, 35 so as to enable the output of the demodulator to be amplified in two different phases by a boostrap circuit including transistor 33. With the switches S 1  and S 2  positioned as shown the circuit demodulates a 405 line television signal positively modulated. For a negatively modulated signal the position of these switches is reversed. When a switch S 3  is connected to contact 37 the output V 0  is obtained via S 2 , N 2  from terminal 38 connected to the normal video detector of the television receiver. The transistors may be MOST field effect transistors. Specification 1,189,579 is referred to.

Abstract: 1325473 Purification of polymers SNAM PROGETTI SpA 4 Nov 1970 [7 Nov 1969] 52550/70 Heading C3P [Also in Division B1] A polyolefin, in the form of a suspension in a hydrocarbon medium, is purified from catalyst metal residues by washing in countercurrent with a mixture of an aliphatic alcohol containing not more than 10 ppm of water and the same hydrocarbon as that used as the suspending medium. The polymer suspension is fed continuously to the top of a column 2 while the solvent mixture is fed to the bottom of the column through line 14. The polymer forms a packed bed through which the solvent rises, the polymer mass being slowly stirred to prevent the development of preferential paths for the flow of solvent. The purified polymer is withdrawn by line 7 together with some clean solvent which is separated in centrifuge 11 and returned to the bottom of the column. Removal of the polymer from the column is assisted e.g. by a rotating wedge 19 and by suitable design of the stirrer 18. The polymers which may be treated in this way are those prepared using as catalyst a transition metal compound together with an aluminium compound, and the method is particularly applicable to those prepared using TiCl 3  and a polymeric aminoalane, -[-AlH.NR-]- n , as described in Specification 1,131,258.
